The effects of biochar (zero, 10 and 20 tons per hectare) and foliar application of Ascophyllum nodosum extract (zero, 2 and 4 ml L-1) were assayed on the growth and physiological responses of Tanacetum balsamita as a factorial experiment based on the randomized complete block design with three replications during 2019-2020 under the field condition.
The interactions of biochar × algae foliar application influenced the dry weight, leaf area, essential oil content and also the protein, phenolics, flavonoids, nitrogen, phosphorus and potassium content of plants. The utmost plant dry weight, leaf area, proteins, phenolics, flavonoids, nitrogen, phosphorus and potassium content was recorded in 20 ton/ ha of biochar × 2 and 4 ml L-1 of algae extract and, 10 ton/he of biochar × 4 ml L-1 algae treatment. The highest chlorophyll index belonged to the application of 10 and 20 ton/ha of biochar × 4 ml L-1 of algae extract. 20 ton/ha biochar × 4 ml L-1 of algae extract enhanced plant height up to 76 cm which was 59% higher than the control. 20 ton/ ha biochar × 4 ml L-1 of foliar treatment increased the essential oil yield in plants.
Conclusion: The overall results revealed that 20 ton/ha biochar along with foliar spraying of 4 ml L-1 algae extract had promising effects on essential oil yield of Tanacetum balsamita. The results with some more detailed studies would be advisable to the extension section.
